changing font and size in Twenty Ten theme (7 posts)

Hi, I'm new to WordPress and built my web site (rockbeareguitars.com) in the Twenty Ten theme in October/November without needing to resort to code, which I don't understand. Nor, looking at the forums, so I understand what a css view is!

Using my Macbook Pro, I was able to change the font for all my body text to my preferred Helvetica 12pt by highlighting and right-clicking, and if you look around the site you can see the results.

It's all this way, except for the homepage whose text I have recently been trying to change but something is now stopping me from modifying the font and size.

Has something changed, either in WordPress or the template? If so, Surely this doesn't constitute an "upgrade"?!?

Don't edit the Twenty Ten theme! Your changes will be over-written the next time you upgrade WordPress or the theme. For this reason, it is recommended that you consider creating a child theme for your customisations.
